为什么我的 iTerm2 上无法使用 Cobalt2 zsh 主题？

Question

我想安装这个 ZSH theme 。我下载了 iTerm2 和 ZSH 主题。

iTerm 主题是通过首选项导入的。 ZSH 主题与所有其他 ZSH 主题一起插入到 ~/.oh-my-zsh/themes 中。

当我打开我的.zshrc 并将ZSH_THEME="bobbyrussell" 更改为ZSH_THEME="cobalt2" 时，什么也没有发生。我重新启动 iTerm 但颜色没有改变。

更新详情：

~ echo $ZSH_THEME
cobalt2

~ echo $PROMPT
%/ ~

文件：~/.zshrc

# Path to your oh-my-zsh installation.
export ZSH=/Users/username/.oh-my-zsh

# Set name of the theme to load.
# Look in ~/.oh-my-zsh/themes/
# Optionally, if you set this to "random", it'll load a random theme each
# time that oh-my-zsh is loaded.
ZSH_THEME="cobalt2"

# Would you like to use another custom folder than $ZSH/custom?

plugins=(git)

# users are encouraged to define aliases within the ZSH_CUSTOM folder.
# For a full list of active aliases, run `alias`.
#
# Example aliases
# alias zshconfig="mate ~/.zshrc"
# alias ohmyzsh="mate ~/.oh-my-zsh"

export PS1='%/ ~ ' 

Answer 1

你的.zshrc 的最后一行export PS1='%/ ~ ' 覆盖了cobalt2.zsh-theme 配置的提示，它设置了$PROMPT（当你source $ZSH/oh-my-zsh.sh 时，主题是来源）。如您所见，export PS1='%/ ~ ' 在source $ZSH/oh-my-zsh.sh 之后，因此它会覆盖之前的值。 （注意$PS1、$PROMPT和$prompt在Zsh中是同义词。）

解决方法很简单：删除.zshrc的最后一行，然后重试。
